T0 @ZZ whom t may concern: Y

'Be it known that I, CHARLES H. Tlsn, a

citizen of the United States, residing at W'inston, in the county of Forsyth and State of North Carolina, have invented new and useful Improvements in Water-Elevators, of which the following is a specification.

This invention relates to that class of waterelevators in which buckets carried hy an endless traveling chai n or belt serve to raise the water from the well and deliver it into a trough in the well-curb.

The object of the invention is to provide a water-bucket of a novel construction, which is attached to an endless chain or belt or other medium for raising and lowering the same, an d is so shaped as to embrace or straddle the wheel or pulley provided at the top of the well for the reception and guidance of the endless chai n or belt carrying the bucket or buckets. By this arrangement the bucket can have a larger waterholding capacity than ordinary buckets without increasing the diameter ofthe well and its curb. Another feature ofthe curb is a novel friction-brake for the guide wheel or pulley over which the bucket-carrying chain passes, said brake being a swinging arm arranged in the same relative position to the guide-wheel as the construction shown in Patent No. 273, 914, dated March 13, 1883, but embracing a somewhat different or improved manner of mounting said brake-arm. The latter, while specially adapted for the guide wheel or pulley of a water-elevator, can also be applied to all kinds of wheels, drums, and windlasses used in hoisting apparatus.

The invention consists in the construction and combination of parts, which will be hereinafter more fully described, and set forth in the claims.

In the drawings, Figure 1 is a vertical sectional View of a well curb or casing,showing the guide-wheel and endless chain in elevation and one of the water-buckets in section, said bucket being in the position it assumes just before discharging its contents. Fig. 2 is a plan or top View of the well-curb, guide-wheel, endless chain, and bucket. Fig. 3 is a face view of the guide-wheel, partly in section, showing the swinging brake-arm in position. Fig. 4 is a longitudinal sectional View ol" the guideor apron, B, carrying any suitable number of buckets, C, for raising water from the bottom of the well and delivering it into a spout or trough, D, on the well-curb. The endless chain B passes over a guide wheel or pulley, E, which is arranged in the well curb or casing, and is fitted on a transverse shaft, F, having its ends journaled in boxes on said curb. rllhe shaft F has a suitable crank-arm, F, or handle for turning the same and imparting the proper traveling movement to the endless chain carrying the buckets. One of the bearings or boxes ot' the shaft is elongated or is constructed in the form of a tube, G, which has a flange, g, for attaching it to the well-curb, as is elearlv shown in Figs. 2 and. lThis elongated bearing or tube has an axial opening for the passage of the shaft, and is formed at its inner end with an eccentrically-disposed projection, G', as is shown in Figs. 3, 4, and 5. rlhis eccentric part 'of the bearing G is encircled by the hub or apertured inner end of a swinging brake-arm, H, the outer end of which engages with the inner periphery of a ring-shaped flange, e, projecting from the side of the wheel or pulley E.v It is evident that by hanging said brake-arm in the eccentric manner shown that the movement or rotation of the wheel or pulley E can take place in one direction; but that a reverse movement thereof is prevented by the forcible binding or contact of the brakearm against the ring-flange e.

It may be stated that the operation of the brake-arm is substantially the same as is described in the Patent No. 27 3,914; but I have in the present instance devised a more perfect and secure manner of mounting said brakearm. The periphery of the pulley or wheel E is grooved and also has transverse notches for IOC the reception and retention of the links com-v prising the endless chain or bucket-carrier. This chain is preferably composed of barshaped links Z), which have interlocking end sleeves and forked portions b2 and b, through which are passed fastening-rivets b", as is seen in Fig. 9.

'Ihe buckets for raising the water from the well an d delivering it into the discharge-trough of the well-curb are composed of a cylindrical shell or body, G, which has a segmental opening or chamber, II', in its middle portion that conforms in shape to the periphery of the guide Wheel or pulley I3. The lateral walls H2 of this chamber serve to divide the shell or body into two compartments, which, how ever, are in communication with each other by the space or opening left between the curved bottom wall of the chamber H and the inner periphery ofthe shell of the bucket. The latter is connected with the chain by fit ting the links thereof at the ends ofthe chamber H, and securing them in place by means ofsuitable rivets passed through the side walls, H2, and the links, as is shown in Figs. G and 7. The bottom of the segmental chamber, which, it .may be incidentally stated, is of the length of two chain-links, has a rib, that engages with the notched periphery of the wheel or pulley E and prevents the bucket from slipping back ward thereon. Thebucket has two openings, h, one for each interior water-chamber thereof, and directly opposite to said opening is a third opening, h4, which has a valve, h5, as is shown in Fig. 6. The valve opens in an inward direction, as is shown in Fig. l, and serves to uncover.its opening as the bucket is taking in water, or is being lled through the other openings, h3.

Itis evidentthat when the bucket is descending into the water that the openings h3 are brought lowermost and that the air displaced by the incoming water is permitted to escape through the opening if, which for the time being is uppermost. Then the bucket is full and is ascending, the position of the bucket is Having thus described my invention, what l. In a water-elevator, the combination of a bucket having a central chamber and waterchambers on each side thereof with a carrier chain or belt and a guide or supporting wheel adapted to enter the central chamber of the bucket, substantially as described.

2. In a water-elevator, the combination of the cylindrical bucket having oppositelylocated inlet and outlet and air openings, and provided with a central chamber, with a carrier chain or belt, and a guide wheel or pulley adapted to enter the central chamber of the bucket, substantially as described.

3. In a water-elevator, the combination of a carrier chain or belt, a water-bucket having a central. chamber receiving the chain or belt and valved inlet and outlet openings, and a supporting wheel or pulley adapted' to enter the said central chamber, substantially as described.

4. The combination of the elongated bearing or tube having an eccentric projection at its end, and the swinging brake-arm journaled or hung onsaid projection, with a wheel or pulley adapted to engage with the brakearm, and the shaft of said wheel passing through the elongated bearing or tube, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
